Potties,are these WW2 era sake cups?

Hi all. Picked these up for no reason other than they intrigued me.The military air mostly. Might they be WW2 ? Any input is always appreciated.
1st one is 31/4 wide


2nd is 2 1/2 inches wide


3rd is 2 3/4 wide


4th (and my fave) is 2 1/4 inches wide

 

I'm not seeing enough depth to the first few for them to be sake cups. They look almost flat but not quite. Maybe for dipping sauce? The last one does look like a cup. How deep?

 

they all are an inch deep,the green one is about an inch and a quarter.I dont know why I said sake,I really thought them sauce dishes!

 

Sauce I can get behind!

 

Sake cups are not really what we call cups - they are more like little dishes. (These are sake cups BTW)

Definitely military though and could be WW11 - not sure - all the ones I have are pre-WW1 and made from lacquered wood. I even have a really really old one, cracked, cost me a dollar many years ago but still my favourite.

 

There are sake cups that are almost flat, but I don't know if that's what these are. Google sakazuki. It seems they are mostly ceremonial. I think sauce dishes are smaller.

 

I see that @ludovic volunteered to help with Japanese translation... has not logged in for a few months, though. Still, thought I'd tag this one. I believe that's the only Japanese volunteer we've had. (EDIT: I should have written "the only volunteer for Japanese that we've had." Ludovic mentioned being French but now living in Japan.)

 

Thanks Fig. Something about these just appealed to me,though oriental isnt my "thing" most of the time.

 

I like them, too -- for me it's just that they are out of the ordinary compared to things I usually see here in Iowa.

 

Thank you ! I see that prices are all over the map ,terribly informative link.
